This document presents an analysis of bounds on the zeros of polynomials with complex coefficients. It begins by reviewing several existing theorems that establish bounds on the location of zeros under various constraints on the coefficients. The main results of the paper are Theorem 1 and its corollaries, which generalize previous theorems by relaxing some restrictions on the coefficients. Theorem 1 establishes bounds on the zeros when the real parts and imaginary parts of the coefficients satisfy certain inequalities involving parameters 了 and . The corollaries specialize Theorem 1 to various cases and relate it back to previous results. In summary, the paper extends the understanding of bounds on polynomial zeros by presenting new theorems with less restrictive assumptions on the coefficient values.
This document summarizes a research paper that proposes a novel reversible data hiding scheme using AES encryption. The scheme consists of three phases: 1) AES encryption of the original image, 2) data embedding by modifying parts of the encrypted image, 3) data extraction and image recovery by decrypting the encrypted image and extracting the hidden data. The scheme aims to securely hide data in images while allowing perfect recovery of the original image. Experimental results show the decrypted image has a high PSNR value of 55.11dB and the hidden data can be successfully extracted.
The document summarizes a study that investigated the effects of adding flyash and silicon carbide (SiC) particulates on the hardness, tensile strength, and wear behavior of an aluminum-copper alloy. The alloy was reinforced with different weight percentages of flyash and SiC using stir casting. Testing showed that hardness, tensile strength, and wear resistance all improved with increasing amounts of reinforcements. Micrographs indicated good bonding between the matrix and particles without fractures at interfaces. Overall, the addition of flyash and SiC improved the mechanical properties of the aluminum alloy for engineering applications.
The document describes the development of a new semi-automatic measuring device system to determine leg and pelvic misalignment. The system uses laser-assisted length measurements, motorized foot platforms, and video footprint analysis to measure body size, leg length difference, pelvic obliquity, and foot pressure points. A prototype was created and is undergoing practical testing in an orthopedic practice. The goal is to optimize the system based on testing and eventually produce it for clinical use in diagnosing misalignments.
Choosing the Best Probabilistic Model for Estimating Seismic Demand in Steel...IJMER
油
This document summarizes research on selecting the best probabilistic model for estimating seismic demand in steel moment frames. The researchers analyzed steel moment frame buildings with 3 to 15 floors using 80 earthquake ground motions divided into groups based on magnitude and distance. Nonlinear dynamic analysis was performed by scaling the ground motions and observing the structural response. The goal was to establish a mathematical relationship between ground motion intensity measures and seismic demand parameters. Based on the analysis results, the best model was determined to be a linear combination of the first and second mode spectral accelerations, as it provided the most accurate seismic demand estimates for frames of varying heights.

This document presents a general framework for building classifiers and clustering models using hidden topics to deal with short and sparse text data. It analyzes hidden topics from a large universal dataset using LDA. These topics are then used to enrich both the training data and new short text data by combining them with the topic distributions. This helps reduce data sparseness and improves classification and clustering accuracy for short texts like web snippets. The framework is also applied to contextual advertising by matching web pages and ads based on their hidden topic similarity.

This document presents research on improving top-k query processing in distributed wireless sensor networks (WSNs) by addressing the challenges posed by data uncertainty and energy constraints. It introduces algorithms such as sufficient set-based, necessary set-based, and boundary-based methods for efficient query processing while adapting to dynamic data distributions. The study emphasizes the need for in-network processing and proposes a cost-based adaptive algorithm that selects the most efficient method based on changing conditions in the network.

Nonlinear Control of UPFC in Power System for Damping Inter Area OscillationsIJMER
油
This document summarizes a research paper about using nonlinear control of Unified Power Flow Controllers (UPFCs) to damp inter-area oscillations in power systems. The paper proposes a nonlinear control method where UPFCs can control their interface bus angles to mitigate power system oscillations. The control method develops a reduced nonlinear model of the network and uses selected frequency measurements from a subset of dominant machines as inputs to FACTS controllers. The effectiveness of using this method with UPFCs to damp inter-area oscillations is validated on a test power system.
